IMPROVEMENT IN PUMPS.

Specilication forming part of Letters Patent No. 56,468, dated July 17, 1866.

To all whom 'it may concern:

Be it known that we, FELIX W. TULLY and THOMAS REEGE, both and each of the city and county of Philadelphia, in the State of Penir sylvania,have invented a new and useful Improvement in Pumps; and we do hereby declare the following to be a full, clear, and eX- act description thereof, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side view, and Fig. 2 a front view.

In both these figures like letters refer to like parts.

rPhe barrel or cylinder of the pump is indicated by the letter A. The piston-rod B is attached at its lower end to a piston or plunger (not shown) moving up and down, as usual in pumps of this character.

G is a pipe passing downward into the cask, vessel, or cistern from which the uid is to be withdrawn. C is an elongation of this pipe, to be attached thereto by the screw-joint shown at the lower end of C, there being a corresponding female screw in C. The length of this additional piece of pipe C will, of course, be determined by the depth of the fiuid in the cask or vessel.

D is a crab or saddle attached to a collar surrounding the tube C and moving freely thereon, but to which it can be firmly aiXed by means of a clamp-screw and nut, as seen at d. The letters c care sharp points of metal proceeding from the under surfaces of the tingers of the crab D, to be driven, if this can be done, into the cask or vessel. The object of this arrangement is to give a firm support to the pump Aand prevent disturbance of the liquid in the cask or vessel by any movement of the tube C C when pumping.

If it be desirable to prevent access of air to the liquor or duid in the cask the pipes maybe packed air-tight as they pass through the orice in the cask or vessel. As these pipes connect the cavity of the cask with that in the pump-barrel A below the plunger or piston, ot' course no air can enter either from without when the connection is thus made air-tight. This is a matter of much importance in transferring from one vessel to another liquidssuch as ale, porter, te-that would soon be injured by free access of common air to them, and the same may be said of those mineral waters whose medicinal qualities depend to a greater or less extent on the gases with which they are impregnated.

E is the discharge-pipe connected with and, of course, opening into the chamber of the barrel or cylinder A.

Any ordinarycheck-val ve maybe introduced at or near this point of connection to prevent the return ofthe fluid through this dischargepipe tothe pumpcylinder. We have given a form to this pipe in the drawings that adapts the device to transferring fluids from casks or other vessels to bottles or other small vessels, availing ourselves of its upper part to give support to the driving-shaft F; but this form is not material. Any other better adapted to the particular purpose may be used. 1n the line of this pipe we introduce a stop-cock, G, that may be used to prevent the waste of material between it and the check-valve, or in case the latter should be defective.

Ahose or other flexible pipe and nozzle may be attached to the end of the discharge-pipe E, as seen at H and H.

1 is a vertical circular disk supported upon and by the shaft F, as seen at f. To the other end of this shaft is attached the crank or handle K, which gives motion to the machinery of the pump. In the drawings, Fig. l, the shaft passes through a cylinder or straight pipe, k, supported by the upper portion of the discharge-pipeE; but this is a mere matter of convenience. Any other arrangement accomplishing the purpose will answer as well as this.

The disk I has two slots cut in it at right angles, crossing each other at the center and extending nearly to the outer edge or periphery. These slots are indicated in Fig. 2 by the letters L and L. 1n these slots move two blocks, l and l', and to them are loosely pivoted the upper end of the link N, while its lower end is also loosely pivoted to the upper end of the piston-rod B.

By this peculiar' mechanical device or arrangement oue turn of the crank or handle K produces two throws of the plunger or piston of the pump, and therefore a single-acting pump constructed on this principle is equivalent to a double-acting one of the same caliber of cylinder acting under the ordinary inluence of a common lever or crank.

AThis description shows clearly that for any ordinary purposes this pump has decided ad- Vantages over those in common use in the amount of fluid it will discharge in given length of time, and if the idea which lies at the foundation of its structure be carried out further by attaching a connecting-pipe between the ltube C or C and the upper portion of the cylinder A a double-acting force power may be constructed with a like increase of eciency as such over any of the ordinary force-pumps in use. It is consequently applicable to all the purposes of a single or double acting force-pump. For instance, liquids of any kind, still or aerated, may be .discharged from one Cask to another, one. room to another, or onestory to another without being exposed to the open atmosphere, or, at least, Without doing them any material injury thereby or becoming dangerous or offensive.

ln bottling Wines, liquors, and the like, by the use of the pipe H and stopcock G the bottle may be filled with the greatest facility to the exact extent required, and, owing to the depth to which the tube C may be carried and the steadiness given to the pump by the crab or saddle D and its fixtures, the duid from a cask or barrel may be almost entirely drawn out and transferred without disturbance to the sediment at the bottom. For purposes of irrigation it Will be of great use, and also for domestic and horticultural purposes. For ships7 pumps, by its greatly increased capacity of discharge over those structures commonly used, it certainly deserves special attention. Although others might be cited, We think these examples sufficient to indicate the merits of our invention. Therefore,

Having thus fully set forth the character and nature thereof, what We claim, and desire to secure by Letters Patent of the United States, is-

1. The combination of the disk I, with its slots L L', blocks l l', and vibrating-link N with a single or double acting lift and force pump constructed substantially in the manner set forth.

2. The crab or saddle l), with its fixtures el and e, in combination with the foregoing and with the pipe C, for attaching and giving support or steadiness to the pump, substantially as described.
